"What can be wrong with this floor?" Liu Shuyuan found that he and Bai Song were not on the same mind line at all. When Bai Song came out to handle the case, the level of excavation of some details was several grades higher than his, so he could only humbly ask: "Don't hide your old man's words, I didn't find it anyway." ”

"Let's come over there, and here, there is a strong well and two weak wells. This hospital is not too big, why two weak electric wells?" Bai Song asked in the corridor with some puzzlement.

“...”

"Why don't you speak? There's no surveillance in this corridor, you can talk to me." Bai Song felt that he couldn't figure it out.

"Uh..."Liu Shuyuan said: "What is a strong electric well? What is a weak electric well? Is it divided according to the 36 volt safe voltage?"

......

"It's not. Chatting, the two of them quickly arrived at the floor of the laboratory, there was no difference from the other side, Bai Song glanced at it and continued to walk up, "The strong electric well is mainly the power supply line, which is generally 220 volts, 380 volts and above high-voltage electricity, mainly the power supply of the building." The weak current well is a fiber optic and telephone cable line, and the voltage of the telephone line is 110 volts, but it is also a weak current. ”

"Strange knowledge has increased..."Liu Shuyuan had a little headache when he heard Bai Song talk about this on this occasion: "So there are many cables needed in the hospital building, so two weak current wells are installed?"

"But the weak current well is very large, and it is not necessary to run from the first floor to the thirteenth floor, generally speaking, a pipe with a diameter of more than ten centimeters is enough to accommodate all the weak current lines. Bai Song said: "This hospital is not a high-tech hospital, can it use so many lines?"

"It's hard to say. When Liu Shuyuan heard this, he seemed to understand something: "Maybe at the beginning of the construction of the hospital, it was 'high-tech' as propaganda? Don't you see that there is still a whole floor idle as a cooperative laboratory of Tianhua Medical University? I estimate that this is all a gimmick, and sometimes, the gimmick is more important than the actual thing." ”

"Well, that's true. Bai Song was persuaded again, he has always been good.

On the thirteenth floor, the two called the elevator, this time it was not the previous elevator, the elevator staff inside was a man, he didn't ask the floor at all, and directly helped the two press the first floor to the bottom of the building.

There are still no special vehicles such as ambulances at the door, and Bai Song breathed a sigh of relief, after all, he still saw the behavior of a doctor giving first aid to a patient just now, and he was really a little worried that he had occupied a special parking space.

Looking around, only one truck carrying medicine is a hospital car, and the rest, not a single car with a special sign is really deserted.

There was nothing to be nostalgic about, Bai Song and Liu Shuyuan got into the unit's car directly and drove away from the hospital.

Halfway through the road, Bai Song suddenly asked, "What time is it?"

"5:40", Liu Shuyuan is very happy, no need to work overtime.

"What time are we going to the hospital?" Bai Song was a little puzzled: "Why didn't you ask us for money when you came out?"

"Well, that's true. Liu Shuyuan also just reacted: "Could it be that our time is less than an hour?"

"How is that possible? It's been a long time in the activity room and the library, and I remember that we should have been in the hospital around four o'clock. We came out of the unit at two o'clock and stayed in the community hospital and health management center for a little more than an hour and a half. ”

"After more than an hour, the charge is 1 yuan per hour, and it is estimated that people are too lazy to charge a dollar. Liu Shuyuan, who has a good family background, never thinks about a dollar.

"Probably. Bai Song drove the car without distraction and went straight to the Economic Investigation Corps.

When he returned to the unit, it was already time to get off work, and Bai Song went to the Qin detachment for the first time and talked about the clues he got from the health management center and hospital in the afternoon.

As for the questions about the hospital, most of them were just Bai Song's conjectures, so when he told the Cao detachment, Bai Song just said that he went around and didn't find any useful clues.

"Is it a health hospital?" After listening to Bai Song's harvest in the afternoon, the Qin detachment frowned, and he didn't say a word for a long time, and Bai Song was a little nervous.

"Okay, I know, don't continue to investigate this matter, I'll tell the Tianbei Branch about the matter when I go back." After the Qin detachment finished speaking, he continued to emphasize: "Tomorrow you continue to interrogate those suspects who have not finished questioning, Xiaoliu has to make up the case file, and tomorrow I will arrange for someone else to accompany you." ”

"But, over there at the hospital..."

"Nothing. The Qin detachment interrupted Bai Song's words: "The matter of the hospital, I just said it very clearly. This matter is considered a confidential matter, and from now on, you are not allowed to communicate with anyone about this afternoon's incident, including Koyanagi. ”

"Understood. Bai Song had a lot to ask, but he nodded.

"Well, also, the day after tomorrow is a May Day holiday, and you've been working hard lately, pay attention to rest. Cao Detachment said: "If you go to travel or go home or something, hand over the fake note as soon as possible, and I will approve it for you." ”

"Thank you, Detachment Cao. ”

"Okay, you go out, and call Xiaoyanagi over by the way. ”

"Good. ”

Bai Song left the house with a heavy heart, found Liu Shuyuan, informed him, and walked to his house.

Liu Shuyuan was still a little puzzled, and wanted to ask Bai Song what was going on, but Bai Song shook his head, didn't say much, and let Liu Shuyuan go directly.

When the Cao detachment said these words just now, although it was not very harsh, Bai Song could see that the mood of the Cao detachment was already very restrained. If it is only this case that the Economic Investigation Corps does not have jurisdiction, then it will not be so.

The Cao detachment is the leader of the detachment, and Liu Shuyuan is the policeman, according to common sense, the Cao detachment should not directly ask Liu Shuyuan to say anything, even if they have any personal relations directly, they should not let Bai Song call Liu Shuyuan.

In this way, there is only one possibility, that is, the Cao detachment will personally instruct Liu Shuyuan on the confidentiality of this matter.

Today is Friday, April 26. Tomorrow is the 27th, so I will go to work as usual. Because next Wednesday is May Day, the holiday time will be Sunday to Wednesday, and of course, next Saturday will go to work as usual.

During the four-day May Day holiday, Bai Song really planned to go out for a walk, but when Cao Detachment said this, he was not in the mood to play.

With thoughts flying in his head, Bai Song pushed open the door and entered his dormitory.

Well?

Bai Song also thought that he had gone to the wrong house, and there were people in the house.

Without going out to see the room number, Bai Song determined that this was his own house from the things he had laid, and immediately greeted the senior in the house.
